John, above, almost had it right with
(1) Eraser
(2) Rubbing alcohol
Actually, it should have been,
(1) Eraser
(2) Very good bourbon
Sip the bourbon slowly over quite a period of time to settle the nerves, being very careful to ingest enough bourbon, but not too much. Sometimes this step may need to be repeated over several days in order to get your preparation just right.
Then use the eraser.

Just kidding, of course!
